Abstract

Poerba YS, Ahmad F (2010) Genetic variability among 18 cultivars of cooking bananas and plantains by RAPD and ISSR markers. Biodiversitas 11: 118-123. This study was done to assess the molecular diversity of 36 accessions (18 cultivars) of the plantain and cooking bananas (Musa acuminata x M. balbisiana, AAB, ABB subgroups) based on Random amplified polymorphic DNA (RAPD) and and Inter Simple Sequence Repeats (ISSR) markers and to determine genetic relationships in the bananas. RAPD and ISSR fingerprinting of these banana varieties was carried out by five primers of RAPDs and two primers of ISSRs. RAPD primers produced 63 amplified fragments varying from 250 to 2500 bp in size. 96.82% of the amplification bands were polymorphic. ISSR primers produced 26 amplified fragments varying from 350 bp to 2000 bp in size. The results showed that 92.86% of the amplification bandswere polymorphic. The range of genetic distance of 18 cultivars was from 0.06-0.67.Key words: RAPD analysis, Musa acuminata, Musa balbisiana, plantain, cooking bananas.

Abstract

Zulfahmi, Siregar IZ, Siregar UJ (2010) Chloroplast DNA variation of Shorea acuminata Dyer in Sumatra assessed by microsatellite markers. Biodiversitas 11: 107-111. Shorea acuminata Dyer is member of the Dipterocarpaceae family. It is ecologically and commercially important in the Indonesian region. In the present study, chloroplast microsatellites (cpSSRs) were used to study the distribution of chloroplast DNA haplotypes and to assess the variation within and among populations of S. acuminata from Riau and Jambi provinces eastern part of Sumatra. Based on chloroplast microsatellite analysis, six haplotypes were observed for S. acuminata,namely haplotype P, Q, R, S, T, and U, respectively. The high haplotype variation was detected in Bukit Barisan National Park (TNBT) population (five haplotypes); it may be due to TNBT population status as national parks (conservation area) under government protection. The value of genetic differentiation measured for S. acuminata was Gst = 0.150. The Gst values in this study is lower than the mean Gst value estimated in angiosperms plant for maternally inherited. Information on the status of genetic variation of the species in this study could be used as scientific consideration in formulating appropriate strategies for conservation and sustainable utilization ofgenetic resources.Key words: Dipterocarpaceae, Shorea acuminata, chloroplast microsatellites, genetic variation

Abstract

Taurusman AA (2010) Community structure of macrozoobenthic feeding guilds in responses to eutrophication in Jakarta Bay.Biodiversitas 11: 133-138. The group of benthic fauna which feed on the same food sources are classified as a feeding guild. The objective of the present study was to evaluate the distribution and composition of macrozoobenthic feeding guilds along gradient of organic enrichment (trophic states) in Jakarta Bay. The result of the present study was shown that at the hypertrophic stations of the bay dominated by species of surface deposit feeding polychaetes such as, Dodecaceria sp., Cirratulus sp., Capitella sp., and Spionidae. The eutrophic zone of the bay was dominated by suspension feeding bivalves Mactra sp., Chione sp. The offshore area (mesotrophic zone)showed a high diversity of species and feeding guilds compared to other areas. The patterns of feeding guilds in the mesotrophic zone indicated a higher stability of macrozoobenthos community, indicated by the presence of deep-deposit feeder (e.g. Acetes sp.), surface deposit feeders (e.g. Prionospio sp.), suspension feeders (e.g. Chione sp.), and carnivores (e.g. Nephthys sp.) in comparable proportions.The structure of macrozoobenthic feeding guilds in an eutrophic coastal water is positively related to the quantity and quality of organic matters (eutrophic states), and the capability of benthic species in adaptation to such environmental condition.Key words: macrozoobenthos, feeding guild, eutrophication, coastal water, Jakarta Bay.

Abstract

Dewiyanti I (2010) Litter decomposition of Rhizophora stylosa in Sabang-Weh Island, Aceh, Indonesia; evidence from mass loss and nutrients. Biodiversitas 11: 139-144. Mangrove is an essential coastal ecosystem that provides nutrients to estuarine and its surrounding environments through its litter decomposition. This vegetation can be considered as an important ecosystem in food web along the coast. The research was conducted in mangrove forest in Sabang-Weh Island, Aceh. Rhizophora stylosa was dominant species of mangrove in the study area that still remains after tsunami catastrophe in 2004. This study was conducted from February to April 2008, and the purposes were to obtain the decomposition rate of senescent leaves and to measure mass loss, and nutrient contents of decomposing leaves under different inundation regime. Three plots were established in each site. Decomposition of R. stylosa leaves were studied by using litter bag technique. They were made of synthetic nylon which had size 20x30 cm and mesh size was 1x1.25 mm2. Senescent leaves were used because they present major leaves on the forest floor and started to decay. Remaining leaves decreased during experiment period because decomposition process had been taking place in the study area. Time required for decomposing a half of theinitial material (t50) was 67 days and 63 days for site next to the land and site next to the sea, respectively. The decay rate can be expressed by the decay coefficient (K) and the results of K were 0.010 and 0.011 (d-1). The value of carbon (C), nitrogen (N), C: N ratio and phosphorous (P) during decomposition periods were no significant difference in sites but significant difference in time. The C: N ratio of decomposing leaves decreased in both sites. Low C: N ratio in the last of observation indicated that R. stylosa leaves weredecomposed easier at the end of observation than that in the beginning of observation.Key words: Rhizophora stylosa, leaves litter, mass loss, nutrients, Aceh.

Abstract

Abbas B, Renwarin Y, Bintoro MH, Sudarsono, Surahman M, Ehara H (2010) Genetic diversity of sago palm in Indonesia based on chloroplast DNA (cpDNA) markers. Biodiversitas 11: 112-117. Sago palm (Metroxylon sagu Rottb.) was believed capable to accumulate high carbohydrate content in its trunk. The capability of sago palm producing high carbohydrate should be an appropriate criterion for defining alternative crops in anticipating food crisis. The objective of this research was to study genetic diversity of sago palm in Indonesia based on cpDNA markers. Total genome extraction was done following the Qiagen DNA isolation protocols 2003. Single Nucleotide Fragments (SNF) analyses were performed by using ABI Prism GeneScanR 3.7. SNF analyses detected polymorphism revealing eleven alleles and ten haplotypes from total 97 individual samples of sago palm. Specific haplotypes were found in thepopulation from Papua, Sulawesi, and Kalimantan. Therefore, the three islands will be considered as origin of sago palm diversities in Indonesia. The highest haplotype numbers and the highest specific haplotypes were found in the population from Papua suggesting this islands as the centre and the origin of sago palm diversities in Indonesia. The research had however no sufficient data yet to conclude the Papua origin of sago palm. Genetic hierarchies and differentiations of sago palm samples were observed significantly different within populations (P=0.04574), among populations (P=0.04772), and among populations within the island (P=0.03366), but amongislands no significant differentiations were observed (P= 0.63069).Key words: genetic diversity, sago palm, chloroplast DNA, haplotype, Indonesia.

Abstract

Budiharta S (2010) Floristic composition at biodiversity protection area in Lubuk Kakap, District of Ketapang, West Kalimantan. Biodiversitas 11: 151-156. A study on floristic composition has been conducted at biodiversity protection area (Kawasan Perlindungan Plasma Nutfah, KPPN) of PT. Suka Jaya Makmur in Lubuk Kakap, District of Ketapang, West Kalimantan. Two sampling methods were used: Point-Quarter sampling (Quadrant method) of 50 m was applied to class of tree, and 2x2 m2 plot sampling to class of sapling. Of 20 sampling units, 48 species of tree (belong to 27 genera and 13 families) and 94 species of sapling (belong to 54 genera and 28 families) were recorded. Shannon-Wiener diversity index (H’) were 3.54 and 3.49 for tree and sapling respectively, while Pielou evenness index (J’) were 0.91 and 0.77 for tree and sapling respectively. Forest ecosystem in this area can be classified as lowland ever wet tropical rain forest which dominated by dipterocarps species. Species of sapling with the highest importance value index were Shorea laevis, Hopea dryobalanoides and Shorea sandakanensis, while that of tree included Dipterocarpus caudiferus, Shorea laevis and Dryobalanops sp. The floristic composition at family level showed comparatively similar pattern with that at other sites inKalimantan although composition at species level was different.Key words: biodiversity protection area, dipterocarpaceae, floristic composition, High Conservation Value Forest (HCVF), production landscape

Abstract

Djuuna IAF, Abbott LK, Van Niel K (2010) Predicting infectivity of Arbuscular Mycorrhizal fungi from soil variables using Generalized Additive Models and Generalized Linear Models. Biodiversitas 11: 145-150. The objective of this study was to predict the infectivity of arbuscular mycorrhizal fungi (AM fungi), from field soil based on soil properties and land use history using generalized additive models (GAMs) and generalized linear models (GLMs). A total of 291 soil samples from a farm in Western Australia near Wickepin were collected and used in this study. Nine soil properties, including elevation, pH, EC, total C, total N, P, K, microbial biomass carbon, and soil texture, and land use history of the farm were used as independent variables, while the percentage of root length colonized (%RLC)was used as the dependent variable. GAMs parameterized for the percent of root length colonized suggested skewed quadratic responses to soil pH and microbial biomass carbon; cubic responses to elevation and soil K; and linear responses to soil P, EC and total C. The strength of the relationship between percent root length colonized by AM fungi and environmental variables showed that only elevation, total C and microbial biomass carbon had strong relationships. In general, GAMs and GLMs models confirmed the strong relationship between infectivity of AM fungi (assessed in a glasshouse bioassay for soil collected in summer prior to the first rain of the season) and soil properties.Key words: AM Fungi, GAM, GLM, land use.
